TECHNICAL FIELD

This invention is regarding towards wetsuits. Especially for Surfing, Wind surfing, diving and other water related sports.

BACKGROUND TECHNIQUE

Wetsuits has several styles. Wetsuits normally used stretchable materials thus it will fit to body which prevent water to come in and it can provide comfortable doing water sports.

Wetsuits preferably to choose right size for its user in order to fit well. If not, water will easily leak into the suits. And it will end up losing thermal function to keep body temperature warm. Thus best way to acquire Wetsuits will be to tailor made to seek perfect fit to your body.

However tailor made will cost very high due to labor intensive process. And to solve problem it can be prepared several body sizes to satisfy most of body types and mass produce them to lower cost.

PRIOR ART DOCUMENT Patent Document [Patent Document 1]

Japanese Patent Application Laid-open No. 2003-252293

Under the subject 1 shows Pre made Wetsuits that will fit standard body styles and sizes. As the nature of Neoprene material of elastic character, it will fit onto body surface well for most of the part similar to the socks character except very wrong sizes.

SUMMARY OF THE INVENTION Problem to be Solved by the Invention

Under the subject 1, Wetsuits uses elastic material combine with several different cut sheet to stitch to combine so that it will expand and shrink in certain direction thus suits will satisfy most of common body types and shapes. However there is unfit able problem that cannot be complying with the technic and material characteristic above. It is the length of the arm and leg.

Thus by producing pre made Wetsuits for several sizes, length of arm and leg cannot be fitted perfectly nor nearly perfect. It may be possible to produce length of arm and leg by every inches against all body sizes but it will be huge variety that will not productive and cost effective.

Longer arm and leg length Wetsuits can be prepared against every body sizes and cut and adjust after purchased so that size and length will be almost perfectly fitted.

The opening portion 50 and FIG. 3 describes Wetsuits opening of arm and legs are normally tube or taper shaped constructed by flat neoprene sheet stitched. And at the end it has stitch 52 to prevent stitched part rip and opened. Thus if to adjust length to cut, then new opening loses stitch 52 resulting opening part stitch to not secure ending up opening part of stitch to lose and finally broke and open the stitch. Another issue of cutting off the opening is the shape character of opening is tapered which means opening part L2 is smaller diameter than L3. Means if to cut the opening to adjust length then new cut opening L4 will have bigger diameter then induce water leaking that defeat wetsuits function of keeping body warm.

This invention was created since to solve problems above. That means it is the Wetsuits which can be mass produced (non taylor made suits) and be able to adjust length of the arm and leg openings to fit perfect or almost perfect. Also to prevent water to leak from new openings.

Means for Solving Problems

This invention will be achieved by every opening shape to be parallel tube shape not tapered and also to have strong stitch lose stopper to have in every several distances from the openings as described in the 21 in the FIG. 2.

Thus this invention is Wetsuits that is produced by certain elastic materials and arms and legs can slide into the tube shape that constructed by flat sheet materials that was stitched. And when to cut off this tube part parallel to the openings in order to shorten the length. Then to have stitch loose stopper to have in every certain distance. So that within this part can be cut and opening stitch will not rip and lose open. The claim 2 described invention is explain the part of opening to make parallel tube shape and to install stitch lose stopper stitch in every certain distance from the openings.

The claim 3 described invention is explaining that it is produced from certain materials which has the part of opening to make parallel tube shape so that arm and leg can slide through. And arm and leg opening certain length part has stitch loose stopper installed onto the stitch of arm and legs of Wetsuits.

Effect of the Invention

According to this invention, every arm and leg openings will have stitch loose stopper to have in every certain distance. So that within this part can be cut and opening stitch. Then it can be cut in between this fixture. Then stitch will not loose father than next stitch loose stopper. So that tube shape arm and leg openings materials will retain the tube shape. Also within this loose stopper portion of the openings, it is shaped parallel thus new cut openings will retain the same diameter and will not change tighten strength at the openings. Because its openings are remaining to be the same diameter. And to retaining the tighten pressure to the openings will prevent water leaking since of the new cut openings.

In this way the Wetsuits can be pre made at certain sizes at longer arm and leg openings with the mechanism mentioned above. Then it can be fitted towards most of the people's body size including length of the arm and leg. Thus this wetsuits can be produced cheaper than fully taylor made customize wetsuits.

FIG. 2: arm and leg openings of this Wetsuits invention and (a) wil. be showing before cut ad adjust. And (b) is the after cut and adjust.

FIG. 3: conventional Wetsuits arm and leg openings to describe and (a) will be (a) wil. be showing before cut ad adjust. And (b) is the after cut and adjust.

MODES FOR CARRYING OUT THE INVENTION

Explain how to execute this invention style of this Wetsuits 10 is, showing on FIG. 1 shows below neck point entire body covered one piece wetsuits is indicated. This style of wetsuits 10 is same as common pre made suits the same it constructed by many fabric and parts stitched together parts by parts. Mainly used Neoprane rubber laminated by fabric to be used. Wetsuits 10 will be normally used around 3 mm thickness.

Wetsuits 10 is stitch is not penetrated to the other side it is called blind stitch Or other method of stitch go through wetsuits material normally called flat lock. This style we use are flat lock system which material sheet is locked strong. And the part of arm and legs of 15, 11, 12 are used this method to produce.

Explaining the part of arm and leg opening part 11

Opening 11 tip part 13 is FIG. 2( a) Indicated, certain length of tube from the opening will be parallel (L1). opening 11 and tip portion of 13 length is optimized and selected, users arm and leg length is suppose different but then they can adjust the length by cutting off the opening end of the wetsuits.

Opening part 11's tip part 13 has stitch loosen stopper has installed. In detail Neoprene rubber sheet is stitch together to be shaped as tube shape.

Alone the tube towards openings, it has stitch horizontal to the tube till the end in order to make tube shape to stitch sheet which is 20. The part of 11, from the opening to up about 10 to 15 cm it has 21 which is to prevent 20 stitch to be lose by cutting suits in order to adjust length. Those 21 can installed closely or far.

Wetsuits 10 is not described by drawings however arm part 11 or leg part 12 are constructed the same way. Thus they are all shaped pararel on the opening part in order to cut to adjust but retain same diameter to fit well and prevent water leaks. 14 also has stitch lose stopper mechanism is installed in certain distance of the opening part as similar function above.

Explaining Wetsuits 10. Arm opening 11 of this suits, as indicated on FIG. 2( b) indicated users arm length to be cut and adjust length.

Tip part 13 has diameter L1 must be parallel shape thus new cut opening diameter L1 is the same as before cut L1 diameter.

Therefor users arm will be fitted by same pressure and be able to retain same water seal effect. Also as a nature of wetsuits that produced by elastic materials which in case diameter is smaller but yet expand to fit onto the users body. Arm and leg opening 12 has tip part 13 has stitch loose stopper installed in several location near opening. If to cut between stitch loose stopper installed, stitch lose will not go farther than next stitch loose stopper installed point. Leg opening will be the exact same way.

Wetsuits 10 has many different shapes. Such as explained material will be Neoprene sheet is normally used. However if the material is elastic and against leak water into the suits and can keep body warm. Then any material can be used. And way to stitch the material to construct suits can be done at any way And stitch loose stopper method can be at any way. Such as big knots stitch on top of stitch, crossing stitch on top of stitch. Glued tape.

And leg opening only can be adjusted such as short sleeve long leg wetsuits.
